“That’s how I am with my kids, you know?” Gonzales continued, adding, “[Victoria is] real active, she’s cool. You know what I mean? She’s all grown up, you know, for her age.”

During their investigation, police discovered a letter written by Victoria addressed to Gonzales, with a red heart cut out on the front.

“I like you because you are funny,” the letter read, according to police documents obtained by PEOPLE.

“I really like you,” the letter continued. “We were [supposed] to go to the zoo today and I just like you.”

Michelle told police she knew Gonzales and Kelley, who had just moved into her home, were sexually assaulting her daughter days before her death, according to interview transcripts. Michelle said she believed Gonzales was having sex with Victoria every day for a month, while she was at work.

Gonzales and Kelley have been charged with kidnapping, child abuse resulting in death and child rape. Martens has been charged with kidnapping and child abuse resulting in death.

They have pleaded not guilty to their charges.

Meanwhile, the community mourns. “I know she is in a better place now, but I can’t believe that happened to her,” Victoria’s former babysitter told a local paper after her death. “She was so young. I miss her.”

Attorney Tom Clark, who is representing Gonzales, tells PEOPLE he is waiting for more evidence to be released.

“We haven’t received DNA evidence,” Clark says. “The allegations against my client are based on what [Martens] said, so the DNA evidence is going to be key.

“If there is no biological evidence that connects [Gonzales] to the crime, the state’s going to have a real hard time.”

Kelley’s attorney could not be reached for comment, and Michelle’s attorney has asked the public to avoid jumping to conclusions until the defense has presented its case.
